Why do they do this? It isn't fair. ?

Celebrities like Gwen Stefani name their kids really weird stuff. Like Gwen named her second son Zuma Nesta Rock. What's up with that? Don't they realize that these kids have to live with these names forever? Or Ashlee Simpson and Pete Wentz named their son Bronx Mowgli? I like these people and everything I just wanted to know whatyou thought of these names?
